The same behavior happens when I try to boot Nemo from the external card.

I don't know what I'm doing wrong... I must have forgotten something, but I don't know what it is...
I have been having the same problem while trying to boot directly this way, but the system booted fine after creating the appropriate item file and updating the menu.

you are placing the item file in a wrong directory(it should be placed in /etc/bootmenu.d/), please re-read the first post carefully before going further.

if you are going to boot nemo make sure you use u-boot version built on the 4th of May or later.

I found that reading /usr/bin/u-boot-update-bootmenu is very useful for learning how the item file parameters should be filled.

example .item file:

please note that if you are going to boot from an external loaction(other than nand) using a ready made uImage, ITEM_DEVICE and ITEM_FSTYPE actually refer to where the uImage is located whether or not it is the same partition you intend to boot from..

you specify the root device (the partition you want to boot from) along with other kernel parameters using ITEM_CMDLINE.

also for some reason, if the target kernel requires nolo atags and ITEM_REUSEATAGS is used instead of ITEM_USEATAGS, the target system won't boot (this even happens with KP when booting maemo).
